WALL-TIE lac/887,018. Specification of Letters Patent. Patented May 5, mos.

Application filed October 29, 1804. Serial No. 230,{92.

T 0 all whom it may concern:

Be it known that we, JULIUS SomnnA and FRANK W BER, citizens of the United States, residing at Pittsburg and Allegheny, respectively, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in VVall-Ties, of which the following is a specification, refer ence being had therein to the accompanying drawing, forming part of the specilication, in which Figure 1 is a plan view of our improved wall tie. Fig. 2 is a sectional view of the meeting courses of a brick wall, showing the tie in position. Fig. 3 is an edge view showin twisted terminals.

ur invention relates to improvements in wall ties adapted for use in brick or other walls lor forming a bond between adjacent layers of brick-work, etc., and consists generally of a strip of sheet metal provided with laterally extending more or less closely adjacent twisted projections or teeth. it is adapted to be embedded in the mortar as shown in Fig. 2, the various extremities being incorporated therewith so as to provide a strongly connected structure, the ties being inserted at intervals within the judgment of the operator, as will be readily understood.

The tie consists ot a sheet metal body 2, corrugated along one or bot-ii sides so as to provide pr'ojectingtongues 3 and intcrvenmg spaces 4, the tongues being preferably rounded at their extremities and similarly rounded at their bases, so that each tongue and. the adjacent space practically form counterparts one of the other. It will be understood however that the tongues may. be of greater or less width than the intervcning 0 enings and that they may be spaced at any( esired distance apart and of any length. in Fig. 3 we show a partial edge'view of our tie wherein the tongues are individually twisted as at 8 so as to be arranged at an. an-

] gle to the longitudinal plane of their edges, whereby eachtongue will present a slo ing face in a longitudinal direction. T ieso twisted tongues may extend for the lull length of the tie or only part way, and their direction may be reversed if desired 21. c. by sloping them oppositely at opposite ends, to further increase. their holding effect. I

' The subject matter of the present application is similar in construction to that of an application iiled by Frank Weber, one of the applicants herein on July 27th, 1904 hearing the Ser. No. 218,359.

These ties are easily and rapidly stamped they are very strong and eilicient and in practicehave been found togive the desired. results in a very satisfactory manner. ()rdinarily the sheet metal ties, usually ol iron or steel, are coated in any suitable manner to prevent corrosion, as by galvanizing, which treatment also considerably'adds to their ap pearance and connnercial advantage.

The ties may be made in any length or thickness to suit the work in view and may be modilied in the features noted or in any other manner, and all'such changes and variations are considered do be within. the province of the skilled mechanic and to be included within the scope of the following claim.

What we claim is:

'A walltio consisting or a sheet metal strip having a series of twisted teeth extending laterally therefrom, a portion of each twisted. tooth lying-above and aportion below the general plane of the body of the strip.
